TW: oldschool transphobia
The thing about "don't use x term for x group" is this discussion really only exists online. Offline, there are many predominantly older people who identify in extremely individual ways that they spent decades fighting to be, that now get told they can't
I know trans men that call themselves lesbians for so many reasons - maybe they never go on T or get any surgeries because its an intrinsic part of their identity and who they are to have the body they do - it bears scars of being in punchups with skinheads and police violence.
They never had the freedom to choose which identity they were - they were dykes for decades before we were born, and they've led the Pride parade with Dykes On Bikes and let countless queer women find safe haven in their home and cared for so many gay men as they died in the 80s.
